This annoying number shows up as "Michigan Call" on my caller ID. Whoever they are, this company also calls from another number (734-388-4584) as well. They sometimes call up to three or four times a day and never leave a message. I'm going to guess that these people are relentless scammers that don't know how to take a hint. Speaking of which, I have a rule when it comes to numbers that I am unfamiliar with. I never pick them up so as to spare myself from the grief and inconvenience when dealing with these kind of people.
